    • A shared storage network system comprises at least one storage client and a plurality of storage servers, each providing a storage portion of the shared storage network system, each storage portion being divided into a plurality of sectors, each sector being divided into a plurality of blocks, a virtual block identifier being associated to each of the blocks such that the entirety of all of the virtual block identifiers of the blocks form a global block address space in which each of the virtual block identifiers is unique. The plurality of storage servers and the at least one storage client are grouped into a plurality of local area networks interconnected with preferred optical channels to form a global network. The at least one storage client is adapted to have read and/or write access to at least one block of at least one of the storage portions associated to one of the local area networks which differs from the local area network of the storage client. The plurality of local area networks are interconnected such that in case of a read or a write access of one of the at least one storage client to at least one of the blocks, the virtual block address of a block to which access is desired is translated into a physical block address to identify the physical block associated with the virtual block. The shared storage network system is further adapted to implement a storage data transmission scheme comprising an optical burst mode flow control and an optical stop-over burst transmission method.
    • 共享存储网络系统包括至少一个存储客户机和多个存储服务器,每个存储服务器提供共享存储网络系统的存储部分,每个存储部分被划分成多个扇区,每个扇区被分成多个块 ,虚拟块标识符与每个块相关联,使得块的全部虚拟块标识符形成其中每个虚拟块标识符是唯一的全局块地址空间。 多个存储服务器和至少一个存储客户机被分组成与优选光学信道互连的多个局域网,以形成全球网络。 所述至少一个存储客户端适于具有与存储客户端的局域网不同的与局域网中的一个相关联的至少一个存储部分的至少一个块的读取和/或写入访问。 多个局域网相互连接,使得在至少一个存储客户端中的一个至少一个块的读取或写入访问的情况下,期望访问的块的虚拟块地址被转换 变成物理块地址以识别与虚拟块相关联的物理块。 共享存储网络系统还适于实现包括光突发模式流控制和光停止突发传输方法的存储数据传输方案。
